METHOD OF MAKING WARDROBE-TRUNK TROLLEYS.

Application filed January 15, 1923. Serial No. 612,819.

To all whom it may concern:

Be it known that I, FREDERICK J. GREENE, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Methods of Making Wardrobe-Trunk Trolleys, ofwhich the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to certain new and useful improvements in wardrobe trunk trolleys and the method of manufacturing the same, and refers more particularly to that type of trolleys comprising one or more supports each including a fixed part or rod member and a tubular part or rod member in telescopic relation thereto to provide an extension.

The supports are usually provided insets with the fixed part or rod member of each set secured to and projected forwardly from the rear wall of the trunk in a suitable manner, the tubular art or rod member being extensible to pro ect beyond the trunk section when open or movable to telescope with the fixed part or rod member preparatory to closing the trunk, the clothes hangers having their ends resting on the supports so that when the trunk is open and the supports extended they may be drawn forward to separate the various garments; and facilitate removal of the desired garment.

When the trunk is to be closed, the supports are contracted and, in the event vof any garment hangers are resting on the fixed rod members, it is desirable that means he provided to insure the movement of the tubular rod members thereunder. fore this has been accomplished by obliquely beveling the inner ends of the tubular rod members as illustrated in Letters Patent No. 1,370,667, granted March 8, 1921, to August Petrie. I

The Petrie structure, while performing the functions imparted thereto, is costly from a manufacturing standpoint in that a tension means is required to resist the too free telescoping of its parts.

It is, therefore, an object of my invention to provide a trunk trolley of that type comprising one or more sets of telescoping parts or rod members in which the means for insuring the movement of the tubular rod Hereto-.

members under the hangers also. provide tension means for restraining too free movement of the parts oft-he trolley with respect to each other.

Another object of vide a trunk trolley comprising one or more sets of telescoping rods in which the inner end oftheouter tubular rod ofeach set is tapered and has a snug fit with the fixed rod to produce a tension and tend to restrain too free a movement of the tubular rod on the fixed rod and, at the same time, provide means to insure the easy movement of the tubular rod under any garment hanger or other article supported from the fixed rod when the trolley is contracted.-

Another object of this invention resides in the provision of an improved method of constructing the tubular part or rod member whereby its inner end has an external bevel ending at a substantiallyfeather edge without disturbing the smooth finish of its exterior surface to facilitate the movement of the tubular rod member under hangers or other articles supported on the fixed rod of the support. 1

In the manufacture of trunk trolleys, it is essential that the surface thereof be polished to give an attractive appearance, and in order to reduce the cost of manufacture it is customary to construct the same of material that has been previously finished, as for instance, a material having its outer face previously nickeled- In view of this it is impractical to produce the external bevel on the inner end of the slide support tubular part by grinding or cutting the exterior thereof and it is, therefore, a further object method of constructing the tubular part of the support by forming a blank of expansible material into a tube, reaming out the inifer end of the tube thus formed on a taper and then contracting the exterior of the previously reamed end of the tubular part inwardly so that its inside diameter at. its extreme inner end is less than that inwardly of the tapered part, whereby a tension is my invention is to proof this invention to provide an improved.

a taper-y 30 applied to the fixed rod of the support and too freeesli ding o f-thetubular part over the fixed par't restrained. With the above and other objects in view whichwill appear as the description proceeds, my inventioniresides in "the novel construction, combination and arrangement of parts substantially asyhereina ftendescribed and more particularly defined by the appended claims, it being" understood that such changes in the precise embodiment of the 11erein uisc1osed in'venuenmay be made as me" within the scape of the claims) *Iii .the accompanying drawings, have illustrated one complete"e'xample of the physical? embodiment of any invention construete'd according to the'bfest mode I have e6 'dev'is'ed' for the practical application "of the 'principles'' thereof," and in which -Figure l is a fragmentary view, partly "tube "after the same has been I reamed out on Rig-"ure 3 is a fragmentary view, partly in section and "partly "in elevation, illustrating the 'man'ner of-re'ducing the outside diameter er the 1 inner end "of the tubular part after the same has been reamed' to produce a taper ontheiouterface-thereof,

Refer-ring now more particularly to the accompanying- 'dra wingsrin which like nunierals designate 'likepart's' throughout the several Views, "'6 represents 'the wardrobe section of trunk, 7 -thedrawer"section and a by a' met'allicmeniber orbrace :9 secured to the walls of the-wardrobe section adjacent its top to provideaguide fla'ngeover which the cover Smay telescope. The trolley gene'rallyfincludes" a pair ofextensible supports each comprising avfixed "part or rod -1nember 10 and af tu bu'lar part: or rod member 12 adapted to' telescope over the fixed part, which 'has" its innerend secured to brace 9 near one side wall'wof the trunksection and its outer end braced against lateral movement and held parallel with the adjacent wall ,by an arm'11, one' end of which is secured to the part 10 and the other to the member9. V j

'The parts 12 provide extensible slide sup ports for'garment'hangers or other articles 13 having suitable means 14: for engaging the trolley supports asillustrated in Figure 5.

Each part 12 is formed from a blank cut from a sheet of expansiblematerial and rolled into a tube, the meeting edges, at its outer end, being cut away to provide a V, as at 15, for the purpose hereinafter described. A'fterbeing formed, the tube inher end is inserted through a die or holding 'member 16 and its inner end reamed out on a taper by a suitable tool 17 to produce a substantially feather edge at its extreme inner end 18.

The inner end is then projected from the die or holding member 16t0 position its reamed part outwardly thereof and a forming die 19 having a tapered recess 20 forced thereover to contract the part of the tube projecting above die 16 and produce an external bevel as depicted in Figure 5t, the cutaway part 15 accommodating thecontracting of the tube end, as will be obvious.

:Theshape given the tube inner end by the forming die is such that the'inside diameter of the end at the feather edge 18 is less than that inwardly of said end and the outside diameterof the part 10 so that when provided having sufficient tension to restrain the too free sliding of the tubular part over the otherpart. This construction eliminates the necessity of tension means such as theusual ball and spring, thus materially simplifying the construction. The arms 11 pass through slots 21 in the tubular rods and the inner ends of said slots are closed, as at- 22,"to provide means for limiting the extension of the tubular rods and preventing their accidental detachment.

' When it is desired to separate the hangers 13, to facilitate the removal of any particular garment, the extension sections 12 are moved outwardly to the positionsillustrated in Figure 5. When the trunk is to be closed, the extension sections are telescoped over the fixed parts 10 and the inner ends 18 of the extension sections will readily slide under any hanger that may be supported directly from the fixed parts.

'With this construction and method it will be readily apparent to those skilled in the art to which an invention of this character appertains that the tubular parts or ex-- 'tensible sections 12 may be manufactured of previously finished material without marring'the same,'that the extensible sections readily ride under any hanger supported directly on the fixed parts when said sections are contracted and that the provision of an independent tension device to restrain free movement of the extensible sections on the fixed rods is eliminated.

What I claim as my invention is:

1. The hereindescribed method of forming a tubular member having a tapered end, which consists in reaming the bore of a tube to a thin edge at one end, and in contracting the reamed end of the tube to produce an external bevel thereon.

2. The hereindescribed method of forming a tubular member having a tapered end, which consists in reaming the bore of a tube to a thin edge at one end, and in contracting the reamed end of the tube to produce an external bevel thereon and bring the thin edge to a diameter smaller than the normal inside diameter of the tube.

3. The hereindescribed method of forming a tubular member having a tapered end,

. which consists in reaming the bore of a tube to a thin edge at one end having a split therein, and contracting the reamed end of the tube to substantially close the split and produce an external bevel thereon.

4. The hereindescribed method of forming a tubular member having a tapered end from previously finished material, which consists in reaming the bore of a tube to a thin edge at one end, and contracting the reamed end of the tube to produce an external bevel thereon having its original finished surface.

5. The method of forming the tubular member of an extensible support for hangers, which consists in reaming the bore of a split and expansible tube to a thin edge at one end, and contracting the reamed end of the tube to produce an external beveled edge thereon and bring the thin expansible edge to a diameter smaller than the normal diameter of the tube.

6. The hereindescribed method of forming trolley members, which consists in forming a cut away portion in the end of a tubular member, and in contracting the end of the tubular member to substantially close the cut away portion and taper the exterior of the member end.

7. The hereindescribed method of forming trolley members, which consists in forming a cut away portion in the end of the tubular member, in contracting the end of the tubular member to substantially close the cut away portion and taper the exterior of the member end, and in reaming the' interior of the member end to provide a thin edge.
